BALL-COCK.

Specification of Letters Patent. Patented D 14 1920 Application filed October 17, 1918. Serial No. 258,614.

To aZZ to 7mm it may concern:

Be it known that I, HERMAN R. KUEHNER, a. citizen of the United States, residing in Camden, Camden county, New Jersey, have invented certain Improvements in Ball- Cocks, of which the following is a specification.

My invention relates to the ball-cock structures of flush tanks, employed for flushing water closets, urinals and the like; and the main object or" my invention is to provide a structure made wholly of non-metallic parts with a view of obviating the deleterious effect which the waters of some localities have upon metal structures and fittings usually employed for this purpose.

To this end I propose to provide a structure in which the parts shall be of nonmetallic material, and while there are many materials which might be employed for the purpose, I prefer to make the structures constituting my invention of some form of vitreous earthenware, such as china or porcelain, or in some instances of glass.

In assembling a structure so made, it may be necessary in some instances, and desirable in others, to employ other materials with the vitreous parts, and of course, it may be de sirable or necessary to employ elastic gaskets between various parts of the structure toinsure water-tight joints, all of which is within the scope of my invention.

These and other features of my invention are more fully described hereinafter, refer ence being had to the accompanying drawings, in which:

Figure 1, is a view in elevation, showing one form of valve structure within the scope of my invention, in position in a flush tank.

Fig. 2, is a sectional elevation ofthe same on the line II-II, Fig. 8.

Fig. 3, is a sectional elevation on the line IIIIII, Fig. 2.

Figs. at, 5 and 6, are views similar to Fig. 2, illustrating modified constructions within the scope of my invention.

Fig. 7, is a sectional view illustrating a detail within the scope of my invention, and

Fig. 8, is a perspective view of one of the parts which may be employed with the structures illustrated in Figs. 4 and 5.

In the accompanying drawings, 1 may represent the bottom wall of the flush tank with which my improved structure is employed, and such tank may be of any ordinary construction and made of any material.

The bottom of the tank receives a metal fitting 2, which may be secured in place by a nut 2*, and to which the pipe for the inlet of water (not shown) is attached.

Mounted in line with this metal fitting and secured thereto by suitable means such as the screws 4, is the casing or body 5 of my improved valve structure; the same being preferably made of vitreous material, and the screws 4 pass through apertured bosses 5* at the sides of the casing or body 5-and into the metal fitting 2. Between the metal fitting, which is preferably provided with a centrally disposed seat 6 and the lower portion of the body or casing 5 which may be recessed at 7, a washer 8 may be placed.

The valve casing is provided with a passage or chamber 9, having a seat 9 near the lower portion of the same for engagement by a valve stem 10 vertically movable in said passage, and said valve stem is preferably made of vitreous material and provided with a gasket l0 at its lower end for engagement with the seat 9*; such gasket being held in place by a screw 11 threaded into a lead filler occupying a recess in the end of said stem.

Projecting above the body of the valve structure are cars 12 which may be apertured at 12 for the reception of a pin 13 upon whichis pivotally mounted a lever 14 for operating the valve stem 10; such lever carry1ng the usual rod 15, to the opposite end of whlch may be attached the usual ball float (not shown). To avoid displacement of the pivot pin 13, the valve casing may be projvided with an external pocket or recess 16 at one side to receive a projecting arm 13 carried by said pm.

At one side of the valve body I provide a chamber 17 into which the inflowing water passes from the chamber 9 through a port 17*, and within this chamber I may place a bafiie 18, preferably of metal, connected to an after-fill pipe 19. This baiile may be L-shape, and one wall is preferably perforated at 20, whereby the water may discharge into the tank; the sound of the inflow being materially reduced by the use of a perforated bafiile.

In the structure illustrated in Fig. 4:, I have shown a separate piece of vitreous material 22, carrying a valve seat 22, which may be interposed between the valve body proper and the metal fitting 2. This piece 22 may be made of porcelain or other nonmetallic material and in some instances it may be constructed to be reversible. For

such purpose it maybe provided with seats on both sides for engagement by the 'end of the valve stem 10, or the washer carried by 5 the same.

"The member 22 maybe provided with annular ribs or progections or annular grooves for cooperative engagement with similarly shaped grooves or projections, as

' the case may be, on the under side of the valve bodywhereby said member may be properly positioned with reference to the same. Thus the member 22 shown in Fig. v4,. and intheperspective view, Fig. 8, is provided withnnannular groove .23 onits upper side'for engagement with an annular rib or projection 24}: on the under surface of the valve body; The under side of the member 22 may be similarly constructed if desired,

but theform shown in Figsf l and S has a plain under surface and is not reversible. In Fig. 5,.however, I have shown a member 22 which is reversible, and this is provided .on both surfaces with annular ribs or 25 projections 24?; that on one side being adapted to engage air-annular groove. 23 on the under surface of the valve body. In .this arrangement, it is desirable to provide a gasket on the under side of the member 22, between the same .and the-metal fitting the valve stem.

The opening through which water enters the valve casing through the piece 22 is preferably divided into a number of apertures so .as to cut down or reduce the force of the entering water. The under side of the member 22 may be recessed in the same manner as the under side of the valve body shown in Fig. -2, with a washerS preferably interposed between the same-and a seat car- -ried by themetal fitting 2. If desired, sections .25 of sheet packing may be employed between the bottom wallof the tank and the ,metal fitting 2.

The valve stem employed with the form .of structure shown in Fig. l, is substantially like those shown in Figs. 1, 2 and 3. In addition it may be provided with lugs 26 and .27, which are designed to limit its movement in the valve body. For this purpose,

the interior of the latter may be provided with an annular flange 28, having a notch 29, and the lug 26 of the valve stem is arranged to pass this shoulder through said 'gIlQtCh 29, being then turned so as to bring itsslottedportionin proper position for engagementby the operating lever 14. The Yotherlug .27 of the valve stem :may rest upon .orflie ,above the shoulder or flange 28 when said stem isin the seated or closed position,

larged internal chamber 99, opening into a body; having lugs 31 at the sides adapted to grooves 32 on the inner wall of said valve body. This structure is provided with a spray chamber of substantially the same type as those shown in the other structures illustrated. The parts of this form of my improved valve structure may be secured together by a single screw P. In this form of the structure, the valve stem is passed into'the body creasing of the valve from below. The interposed member 22 is reversible;. being provided with seats 22 on both its upper and lower face, and having annular ribs or projections 23 for engagement with annular grooves 24on the under face of the valve body. A gasket may be interposed between the sameyand the metal fitting 2.

In the structure shown in Fig. 6, the delivery chamber 17 :may communicate directly with the chamber 9 and the valve bodymay be secured to the metal fitting by a. single screw t The valve body carries the seat for the valve stem which may be provided with the usual washer, and the metal fitting may have an annular rib or projection 24? adapted to engage an annular groove 23 on the under side of the valve body whereby the latter may be positioned with respect thereto. The operation ofthis valve structure is substantially like those illustrated in the other views.

In Fig. 7, I have shown another arrangement in which a valve stem of substantiallythe same character as that illustrated in Fig. .4, is employed, but instead of carrying a washer at the lower end of thesame, such end is shaped to form a seat which .may be adapted to engage agasket, or sheet packing 34 interposed between the same and the bottom of the valve structure, or an interposed member 22 of the general type shown in Figs. 1 and'5, and which may be reversible. This valve stem may have the lugs shown on the form of valve stem 'illus trated in Fig. 4:-

To facilitate operation ofthe valve stem by the lever, such valve stem may be provided with a roller 35, adapted to a cross aperture 86 forming .a seat or journal in the body of thestem; which roller is preferably of porcelain and with which the end of the lever en a e The interposed member 22 may be of any Suitable construction, and when employed forms the bottom of the valve body or cas ing 5. As shown in Fig. 4: it has a valve seat on its upper side and an annular groove concentric to the same to receive an annular rib carried by the valve body; the under side being centrally recessed, and a number of relatively small apertures being provided for the passage of water. In the form of structure shown in Fig. 5, the plate is pro vided with annular ribs concentric with the annular valve seats; both faces of the member being of the same character. It will be understood, of course, that while it is pref erable to provide the same with valve seats, it may have an annular groove or an annular rib surrounding the said valve seat, as may be desired, for cooperative engagement with an annular rib or an annular groove in the under side of the valve body; either arrangement being within the scope of my invention.

While I have set forth certain specific embodiments of my invention and have shown my improvements as embodying certain definite details of construction, it will be understood that I do not wish to be limited to .the precise constructions shown and that the following claims are designed to cover my invention as illustrated and described as well as any equivalent construction embodying the use of non-metallic material, vitreous or otherwise, employed for a similar or equivalent purpose.
